Installation:
No special installation is required for this program.
E_spw consists of a single .exe file which can be copied
to any convenient hard disk directory.
From within Windows, e_spw can be started like any other
Windows application, i.e., by entering its filename in the
Run window of Progam Manager, or by double clicking its
filename in File Manager.
From DOS, e_spw can be started from the DOS command line
as "win drive:\path\e_spw".
If desired, the e_spw icon can be added to the "Windows
Applications" window. Refer to the Windows Setup program
instructions to do this.
Description:
E_spw is a Mechanical Engineering application written
to run under MS Windows Version 3.0 or later.
E_spw allows an engineer or machine designer to quickly
size standard shaped profiles for 2D Properties: Area,
Y-bar, Moment of Inertia, Section Modulus, Radius of Gyration.
This small program operates much like a section properties
program for a hand-held calculator, but with a graphic
(point and click) Windows interface. Although the program
is fully functional through the keyboard, the use of a mouse
increases its efficiency.
The program consists of 2 main windows. The e_spw opening
window provides control of the System and local menus, and
allows selection of a particular profile. Once a selection
is made, a pop-up dialog box gathers inputs and calculates
outputs. Details of each window's operation are given on
the following pages.
Planned updates for this program include:
1) expanding the number of profiles.
2) adding a module for user-drawn profiles.

E_SPW Dialog Box
Edit Controls:
Edit controls are provided for inputting size parameters:
d[in], b[in], d1[in], t[in], t1[in]
Edit controls filled with 0's are inactive in context with the
selected profile.
Active edit controls are initially filled with default values:
d: 10.0[in]
b: 10.0[in]
d1: 9.0[in]
t: 1.0[in]
t1: 1.0[in]
The maximum value for any edit control input is 1.0e5. Inputs
consisting of non-numeric or alphabetic strings will be read
up to the first non-numeric character.
Edit control spin buttons (mouse only) will increment @ 0.0625"
steps when single clicked. (for inputs < 1000.0")
Dialog Controls:
There are 4 pushbutton controls for the dialog box:
[Close] - Closes the dialog box.
[Calc] - Forces a calculation/re-calculation of program outputs.
[Clear] - Clears (0's) all active edit controls and all outputs.
[StoPrnt] - Saves to memory all current inputs and outputs.

Printer Operation:
Description:
Printing operations are directed by Windows Print Manager using
Windows "default" printer.
E_spw was originally written for Windows 3.0 and printing commands
sent to Print Manager used Windows System font for text information.
This is the font Windows uses for displaying text in caption bars,
menus, etc. Transfer of the bitmap images requires the printer be
capable of bit-block transfer (BitBlt and/or StretchBlt) operations.
At the present time e_spw does not display a "Cancel Printout" box
during printing operations. If necessary, printing can be halted
by pausing operations from within Print Manager, and closing Print
Manager's window.
Controls:
As noted before, the e_spw dialog box StoPrnt button is used to
store data for later printout. Data for 1 to 5 dialog boxes (profiles)
are saved in the form of a printer "queue".
Two menu choices are available through the e_spw main window Printer
pull-down menu. "Start Printer" will send the printer queue
(1 to 5 profiles) to Print Manager. "Clear Printer" will clear the
queue and dump all existing data. Any data left in the queue when the
program is terminated are lost.
